| 摘 要： | 研究了平流层球载系统的方位控制问题.介绍了吊篮方位控制系统工作原理并建立了其数学模型,控制系统采用反作用飞轮子系统实现吊篮方位的高精度控制,并采用反捻装置子系统实现对飞轮电机的卸荷以及对干扰力矩的解耦控制.针对球载方位控制系统,提出了一种带调节因子的新型非线性PID控制器,控制器根据指令跟踪误差自动调整增益参数,能够克服传统PID控制器难以协调快速性和超调量的缺点.仿真与试验结果表明,吊篮控制方案以及非线性PID控制算法能够准确实现球载系统的方位跟踪.

| Abstract: | The stratospheric balloon-borne gondola attitude control system is discussed.The attitude control scheme is introduced,and the system mathematical model is established.The attitude control system uses reaction wheel subsystem to control the balloon-borne attitude accurately,and uses the decoupling mechanism subsystem to decrease the speed of the wheel motor and decouple disturbance torques.For the stratospheric balloon-borne gondola attitude control system,a new nonlinear PID controller is proposed,which ca... |
